All-reliable-point out ultraviolet lasers are commonly used in the fields of mechanical flaw detection, lithography, micromachining and drugs for the benefits of smaller quantity, prolonged lifetime, superior effectiveness, fantastic beam high quality, wide tuning and narrow spectral line, and so on. Employing significant electrical power in the vicinity of-infrared coherent mild supply as the fundamental frequency source depending on nonlinear tuning engineering, producing ultraviolet coherent radiation by multistage frequency conversion is considered a crucial strategy to establish the ultraviolet coherent gentle resource.

全固态紫外激光器以其体积小、寿命长、效率高、光束质量好、调谐范围宽、谱线窄等优点，广泛应用于机械探伤、光刻、微加工和医学等领域，等，利用大功率近红外相干光源作为基于非线性调谐技术的基频源，通过多级变频产生紫外相干辐射被认为是发展紫外相干光源的重要途径。紫外相干光源的关键问题是研制紫外波段的非线性光学变频晶体。非线性光学晶体是实现频率变换的条件之一，因此对非线性光学晶体的生长、尺寸、损伤电阻、转换效率和允许的参数范围提出了越来越高的要求。
Alternatively, the beam excellent of the higher energy DUV laser would turn into worse as a consequence of more severe thermal and nonlinear results. As a result, the frequency conversion procedures should be very carefully made to mitigate the aforementioned effects. So, a high-electricity DUV laser for the FHG of one μm with a fantastic beam excellent may be acquired and will be effective for getting the shorter wavelength DUV lasers including 193 nm by SFG.
Mainly because of the thermal lens impact from the sound-condition lasers, In case the heating management is insufficient, It's not at all simple to get the stable-point out laser with a large electric power in addition to a higher beam good quality concurrently. Lately, with the development of the thin disk laser and one-crystal fiber (SCF) laser, a high-electric power laser at the basic wavelength (1 μm) had been realized with a superb beam high-quality Despite having a TEM00 method beam [4,24], which would be great candidates for the elemental on the DUV laser era. One more candidate for the basic could be the substantial-ability fiber laser which might be realized by coherent beam mix with M2 worth below 1.

In the scientific and industrial applications, the beam high quality in the DUV laser can be a significant parameter. Especially, the beam good quality on the DUV laser substantially impacts the laser machining final results. The beam high quality from the DUV laser is set by that of the fundamental laser as well as crystal to the frequency conversion. Lately, a substantial-energy DUV laser (>ten W) at 258 nm was reported that has a beam high quality of M2 < one.5, which was created by FHG of a Yb:YAG laser at 1030 nm using the CLBO crystal [thirteen]. This laser would result in an even better laser machining outcome compared to the earlier DUV lasers with much larger M2.
